Abstract: The present technology relates to an information processing device, an information processing method, and a program capable of efficiently and highly accurately creating distribution data on geomagnetic fields and the like (electric fields, magnetic fields).

Abstract: In a behavior measurement device (20a) (information processing device), a linear movement detection unit (44) determines, based on a position (P) of a user (90) measured at a predetermined time interval, whether or not the user (90) is linearly moving and detects a movement amount and a movement direction (?0) of a linear movement of the user (90). A rotational movement detection unit (42) detects an amount of change in an orientation of the user (90). Then, in a case where it is determined that the user (90) is linearly moving, an orientation calculation unit (43) calculates an orientation (?) of the user (90) at a position where the user (90) is determined to be linearly moving based on a detection result of the rotational movement detection unit (42).
